The Miami Herald reported had reported that James would have the knee examined by team doctors, but the source told ESPN.com that James was examined Sunday in New York by Knicks team doctors, who determined that he avoided serious damage to the knee. The website reported that James' knee responded well during the flight to Minneapolis, and he would not undergo an MRI, according to the source.

James appeared to hyperextend his left leg and then grabbed his knee after going for an alley-oop dunk in the third quarter of the Heat’s 99-93 victory against the Knicks.

It was a scary moment for James, the defending-champion Heat and the NBA, the Herald noted.

“I was concerned,” James said after the game. “I’m still concerned a little bit.”

After testing out the knee, James stayed in the game, finishing with 29 points and 11 rebounds in Miami’s 14th consecutive victory.

“I was able to finish the game strong but things are always a little worse the next day,” James said Sunday. “We’ve got to fly to Minnesota, but I believe I’ll be in the lineup (Monday), though.”

James said he expected the knee to swell during the flight. Although James was only a little scared at the time of his injury, Chris Bosh said he was very concerned.

“He always does that stuff,” Bosh said. “He’s like Superman. We never expect him to get hurt. Fortunately, it wasn’t anything serious.”

James put away the win over New York with a steal and resounding dunk with 23 seconds to play.

"His motor is limitless. I don't want to take that for granted. I don't just want to assume that he can play 40-plus minutes, but he had to do it on both ends," Heat coach Erik Spoelstra said. "Couldn't get him out in the fourth quarter, and if I would have tried, he probably would have strangled me.

"He was strong and was at his strongest after 40 minutes of basketball."
